I do too. I was just asking how they get you to pay a double fare if they have to drive back.

Quick story: At Danang airport I ordered a Grab car. While I was looking at my phone and the cars, a guy came up to me and said he was a Grab driver. He asked to see my phone, then canceled my ride! I realized when we got to his car that it wasn’t the correct license plate. I wanted to walk away, but my male friend said “let’s just go”. I was seething in the back seat thinking this guy was expecting me to pay the full Grab fare without having to pay a commission and probably not properly insured plus I couldn’t charge it to my credit card! I didn’t have a lot of cash, so when we got to hotel, I short paid him 20-30%. When he started to complain, I told him to report me to Grab and walked away!

I could see the same thing happening if someone asked me to pay a double fare.
